How do I fix this Internal compiler error?

-----CompilerOutput:-stdout–exitcode: -1073741819–compilationhadfailure: True–outfile: Temp/Assembly-CSharp.dll



  • Finished compile Library/ScriptAssemblies/Assembly-CSharp.dll
    Internal compiler error. See the console log for more information. output was:

I looked for the Assembly-CSharp.dll file and it is nowhere to be found!

You may need to delete your Project files (specifically all of the assembly and solution files in your project’s root directory) then perform a resync your Monodevelop project (look in the Assets menu for “Sync MonoDevelop Project”), but you should make a backup of your project prior to trying this, just in case. You could also just try the sync by itself and see if that fixes the problem.
